Question

In the 'default' layout for my Lithium install I have the following code:

<?php echo $this->html->script(array('jquery-1.7.1-dev.js')); ?>

For all normal requests (e.g. /path/to/framework/users/login, where Users is a model and there is a UsersController::login method) this is rendered correctly as:

<script type="text/javascript" src="/path/to/framework/js/jquery-1.7.1-dev.js"></script>` 

However, in views that are rendered by my error handling code the /path/to/framework is omitted and it is rendered as:

<script type="text/javascript" src="/js/jquery-1.7.1-dev.js"></script>

Why is the helper not rendering the path correctly in this case?

Error-handling approach

My error handling approach is based on a number of online tutorials. In config/bootstrap/errors.php I have:

$exampleConditions = array('type' => 'Exception');
ErrorHandler::apply('lithium\action\Dispatcher::run', $exampleConditions, function($info, $params) {
    return ErrlogsController::handleError($info, $params);
});
ErrorHandler::run();

In the ErrlogsController class I have:

public static function handleError($info, $params) {
    // (Code to save error info to DB omitted from example)
    $view = new View(array(
        'paths' => array(
            'template' => '{:library}/views/{:controller}/{:template}.{:type}.php',
            'layout'   => '{:library}/views/layouts/{:layout}.{:type}.php'
        )
    ));
    return $view->render('all', array(), array(
        'template' => '404',
        'controller' => 'errlogs',
        'layout' => 'default',
        'type' => 'html'
    ));
}

I have code dived as deep as lithium\template\view\Renderer::applyHandler and the File adapter which do the actual rendering to try and understand this behaviour, and I have also tried adding an 'elements' key to the 'paths' array for $view but I am a bit stuck. Any suggestions or help is much appreciated.

Background

The below two links show how to use ErrorHandler::apply function (as in above code) and also ErrorHandler::config. Both use the same approach as in the above code to render a view, and the first is also tangentially interesting to this post though because it also shows how to handle different types of errors differently.

• Example one – masom
• Example two – Lithium wiki – shows how to use the ErrorHandler::apply function

Components of the framework get their application base path information from the Request object, which the View class delegates to its helpers, unless of course it hasn’t received it itself.

In your case, you could either pass it in the 'request' key to View‘s constructor, or update to a more modern version of error handling code, as per this: https://github.com/UnionOfRAD/framework/blob/master/app/config/bootstrap/errors.php
